CHAPTER 1: INTRODUCTION In ISRO, a good number of contract workmen are deployed to carryout construction,
maintenance and other related works and these also includes accident-prone activities.
The analysis of the incidents in ISRO reveals that a large number of such incidents
involved contract workforce which in turn have resulted in either casualty or injury,
besides leading to property damage and operational interruptions.
The reasons for accidents are mainly due to unsafe act, unsafe working condition,
lack of training and awareness, inadequate safety management, equipment failure and
poor house keeping. It is seen that unsafe acts and unsafe conditions contribute
approximately 88% and 10% of all accidents respectively. It is also said that a safe and
alert workmen are safer in unsafe condition than an unsafe and un-alert workmen in
safe condition.
During execution of various works at ISRO centers/units, contractor’s personnel are
likely to be exposed to different types of hazards. Similarly, unsafe acts of contractor’s
personnel may generate hazards for Departmental staff and/or workmen of other
contractors working at the site. Such unsafe acts may also pose danger to the existing
installations and even to general public. In order to improve the level of safety
compliance, the contractor safety is of paramount and utmost importance and there is a
need to institute a good contractor safety.
This manual is prepared to facilitate safe working during execution of contract works at
ISRO centers/units.
CHAPTER 2: PURPOSE The purpose of this manual is to establish, implement and execute a practical, sound
and effective program for the prevention of incidents that cause or may cause injury to
person or damage to property, as well as the assignment of specific responsibilities to
contractors for compliance. These safety requirements have been designed to assist all
contractors, their supervisors and workmen to identify, evaluate and subsequently
control various activities or conditions to reduce the possibility of any undesired incident
within their respective area of contract responsibility.

CHAPTER 3: SCOPE 3.1 The provisions of this Safety Manual shall be considered minimum requirements
necessary to all works performed inside the premises of ISRO centers/units and on
ISRO jobs carried out outside the ISRO premises.
3.2 All contractors are required to ensure that they and their employees, sub-
contractors, suppliers, vendors and visitors, while on the ISRO job site, comply with the
provisions of this manual.
3.3 Contractors shall review and educate their employees about the stipulations of this
manual that are appropriate to the work to be performed.
3.4 This manual does not replace existing site procedures or operational specifications.
Approved, site-specific procedures must be followed where applicable.
3.5 This manual does not relieve contractors of their responsibility towards safety,
health, and environmental compliance envisaged under law, code or statutory
requirement.
CHAPTER 4: GENERAL INFORMATION 4.1 The purpose of the contractor safety program is to establish, implement, and
execute a practical and effective method for preventing accidents, illnesses, and injuries
and protecting the environment.
4.2 This Contractor Safety Manual will help contractors and their management to
recognize, to evaluate, and to control hazardous activities or conditions within their
areas of contract responsibility.
4.3 This manual defines how the safety program will be administered, identifies
responsibilities, and ensures control of work area safety.
4.4 Relevant provisions of this manual apply to all contractors. Contract agreement
signed with contractors and the provisions of this manual are intended to complement
each other to ensure safe working conditions; however, in the event of a conflict
between the provisions of this manual and the terms of a specific contract, the matter
shall be referred to the Engineer-in-charge immediately of any such conflicts.

4.5 The provisions of this manual apply to all ISRO centers/units; however, each center
may have specific safety rules and regulations that apply when a contractor performs
work in that center/unit. Contractors are responsible for following the specific safety
rules and regulations applicable to the respective ISRO centers/units.
4.6 Throughout this manual, reference to a contractor means the contractor’s company
and the companies of their subcontractors, consultants, vendors, and suppliers.
Reference to contractor’s management means personnel responsible for managing,
supervising or directing contract activities and employees. 4.7 Non-compliance of safety or environmental requirements is treated as non-
compliance of contract agreement, and may result in work stoppage or employee
removal from the premises. Willful or repeated non-compliance may result in contractor
dismissal and contract termination.
4.8 The Contractor Safety Manual is an important part of the ISRO’s safety program and
will be issued as part of the contract documents. Contractors must ensure that their
employees, subcontractors, consultants, vendors, suppliers, and visitors comply with
the provisions of this manual while on ISRO premises.
4.9 The Contractor Safety Manual is a supplementary document to statutory rules,
codes, and regulations having jurisdiction, and does not negate, abrogate, or minimize
any provisions of these rules, codes, and regulations. It is intended to supplement and
enforce the individual program of the contractor and to coordinate the overall safety
effort. Contractors are responsible for the safety and health of their employees,
subcontractors, consultants, vendors, suppliers, and visitors while in ISRO premises.
4.10 Safety is considered an integral part of quality control, cost reduction, and job
efficiency. Managers and supervisors are accountable for the safety performance
demonstrated by their employees.
4.11 Contractor’s managers and supervisors are responsible for preventing incidents or
conditions that could lead to incidents, injuries, illness, or fatalities. The ultimate
success of the safety program depends on the cooperation of every employee. The
contractor’s management must ensure that safety rules and procedures are enforced
and that effective training and education programs are employed.
